U.S. Nuclear Regulatory Commission ND-21-0434 Enclosure Page 2 of 3 ITAAC Statement Design Commitment 13.a) Controls exist in the MCR to trip the RCPs.

Inspections. Tests. Analyses Testing will be performed on the RCPs using controls in the MCR.

Acceptance Criteria Controls in the MCR operate to trip the RCPs.

ITAAC Determination Basis Testing was performed in accordance with the Unit 3 component test package work order (Reference 1)for Reactor Coolant Pump(RCP)trip testing to demonstrate controls in the Main Control Room (MCR)operate to trip the RCPs (i.e., RCS-MP-01A, RCS-MP-01B, RCS-MP-02A, RCS-MP-02B). Soft controls from the Plant Control System (PLS) were used to generate an RCP trip signal to the four RCP breakers controlled from PLS. The breaker for RCP 1A is ECS-ES-31, the breaker for RCP 1B is ECS-ES-41, the breaker for RCP 2A is ECS-ES-51, and the breaker for RCP 2B is ECS-ES-61. Local inspection verified the PLS trip signal caused the listed RCP breakers to open.

The Unit 3 component test results (Reference 1) were reviewed (Reference 2)and confirmed that controls in the MCR operate to trip the RCPs.

Reference 2 is available for NRC inspection as part of the Unit 3 ITAAC 2.1.02.13a Completion Package (Reference 3).

ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company(SNC) performed a review of findings pertaining to the subject ITAAC and associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.1.02.13a (Reference 3)and is available for NRC review.

ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.1.02.13a was performed for VEGP Unit 3 and that the prescribed acceptance criteria are met.

Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed, ITAAC compliant condition in accordance with approved plant programs and procedures.
